Title: Improvements in and relating to wagon-loading booms
Inventor: HENSON ROY THOMAS
IPC: B65G67/00
Filed: 1959-09-26
Abstract: 886,595. Delivering material to trains of moving wagons. SIMON-CARVES Ltd. July 21, 1960 [Sept. 26, 1959], No. 32805/59. Class 78 (4). A yielding device 18 prevents lumps of coal or other material being jammed between a pivoting conveyer 6 and a shoot device 9, 10 which diverts the stream of material delivered by the conveyer 6 from one wagon 4 of a moving train to the next. The conveyer 6 can be lowered about its shaft 2 to deliver material directly to the bottom of a wagon 4. As the wagon 4 is filled the conveyer 6 is raised until, as the wagon 4 leaves the end of the conveyer (travelling to the left in the Figure) the conveyer 6 is raised to deliver down the shoot 9. As a further wagon 4 comes into position to be loaded the conveyer 6 is slightly lowered so that its stream of material is delivered against a deflector plate 10, and is subsequently lowered to the bottom of the fresh wagon. The deflector 18 comprises a flap pivoted at 19 and counterbalanced by springs or weights.

Abstract: 1487157 Electronic timepieces DAINI SEIKOSHA KK 6 Aug 1975 [23 Aug 1974] 32894/75 Heading G3T In an electronic timepiece having a crystal controlled oscillator circuit, the oscillator frequency is adjustable by selectively operating a switch S Fig. 2 so as to step a ring counter 4 a logic "1" at any output from which opens a respective gate G2, G3, G4 to connect a respective capacitor C 2  C 3  or C 4  into the oscillator circuit comprising an inverter I, crystal Q, R 1 , R 2  and C 1 . Simultaneously current is fed via the respective gate to a respective transistor T 2 , T 3  or T 4 , the base electrodes of which receive pulses from an output a of a frequency divider 1. Consequently a lightemitting diode D2, D3 or D4 is flashed to indicate that a corresponding capacitor C 2 , C 3  or C 4  is effective in the oscillating circuit. A 1 Hz output from the divider 1 increments a seconds counter 2, the output of which increments a minutes counter 3 which in turn increments an hours counter (not illustrated). Correction of the seconds, minutes and hours display can be effected by operation of switches S, m or h respectively.

Title: Improvements in or relating to multiplex signalling systems
IPC: H04B14/08
Filed: 1954-11-15
Abstract: 794,031. Multipled systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 15, 1954 [Nov. 13, 1953], No. 33078/54. Drawings to Specification. Class 40 (4). [Also in Groups XL (b) and XL (c)] Two signals f1, f2 modulate respectively the positive and negative half-cycles of a carrier and at a receiver the carrier frequency is reproduced and used to detect synchronously in turn the signals either directly or by controlling the frequency and phase of a local oscillator for demodulating the composite carrier. The transmitted signal may be formed. by multiplying f1, f2 respectively by (¢+cos # o t) and (¢ - cos # o t), then taking the difference f1 (¢+cos # o t) - f2 ( ¢- cos # o t) and limiting by a filter this difference to a frequency band with upper value N, where No= # o /2# is the carrier frequency so that only the lower sideband is passed (the filtered sideband varying alternately between f1 and f2 in maximum amplitude). At the receiver a narrow pass-band filter with response anti-symmetrical about the frequency No reproduces the carrier frequency No, or if the response is symmetrical, its output may be limited as regards both positive and negative peaks to form a rectangular wave which is differentiated and used to synchronize a pulse generator of recurrence frequency No from whose pulses, applied to a filter, a sinusoidal frequency No is obtained. In either case values (¢ Œ cos # o t) are obtained, e.g. one from the other by a delay network, and multiplied with the received carrier in product demodulators from which the original signals f1, f2 respectively are obtained. If the signal bands f1, f2 extend beyond frequency No an additional term cos 2 # o t must be added to the product terms (¢ Œ cos # o t), both at the transmitter and receiver. To this end the pulse generators of recurrence frequency No at the transmitter and receiver apply their pulses to a filter with cut-off frequency between frequencies 2No and 3No so that the additional term cos 2 # o t is obtained. The signals f1, f2 may be stereoscopic or independent audio signals or colour television video signals. The carrier may be modulated on a main carrier transmitted by radio, or may be directly transmitted by radio or by cable. Specifications 776,989, [Group XL (c)], and 778,406, [Group XL (b)], are referred to.

Abstract: <PICT:0937242/IV(a)/1> <PICT:0937242/IV(a)/2> In a continuous process for epoxidizing a liquid ethylenic compound by reaction with a carboxylic peracid, the ethylenic compound is fed into one end of a reaction zone and passed in continuous countercurrent contact with an aqueous phase containing an aliphatic carboxylic acid, hydrogen peroxide and a carboxylic peracid, aqueous hydrogen peroxide being fed into the reaction zone at the opposite end to the ethylenic compound, the carboxylic acid being fed at the same end as the hydrogen peroxide or at points between the two ends, and the peracid being formed in situ by reaction between the carboxylic acid and the hydrogen peroxide.  The ethylenic compound may be an ethylenically unsaturated acid, ester, alcohol or hydrocarbon.  The carboxylic acid contains from 1 to 8 carbon atoms, and may be mixed with an acid catalyst, e.g. sulphuric or phosphoric acid.  The carboxylic acid is present in an amount of 0.25 to 1 mole per mole of ethylenic unsaturation to be epoxidized; the hydrogen peroxide, which is used as a 27 to 98% by weight aqueous solution, is present in an amount of 1.0 to 1.2 moles per mole of ethylenic unsaturation.  The ethylenic compound may be mixed with a nonreactive, water immiscible, hydrocarbon solvent.  The reaction temperature is from 30 DEG  to 100 DEG C.  The reaction may be carried out in apparatus as shown in Fig. 1, where the ethylenic compound flows from a vessel 18 up through a packed column 10 against aqueous droplets containing carboxylic acid, hydrogen peroxide, and carboxylic peracid produced by flowing in carboxylic acid from a vessel 28 and aqueous hydrogen peroxide from a vessel 38; epoxidized material is removed by outlet 14 and aqueous solution by outlet 50.

Carboxylic acid is fed to each reservoir from a vessel 156, and aqueous hydrogen peroxide is fed to the top of the column from a vessel 176.  Epoxidized material is removed at outlet 140, and aqueous solution at outlet 144.  In examples butyl oleate, soybean oil diluted with heptane, and methyl oleate, are epoxidized using glacial acetic acid mixed with sulphuric acid and with phosphoric acid, and formic acid mixed with phosphoric acid, and aqueous hydrogen peroxide.  Other materials mentioned which may be epoxidized are cottonseed oil, oleyl oleate, olive oil, the methyl and butyl esters of soya fatty acids, the methyl ester of cottonseed fatty acids, oleic acid, oleyl alcohol, dodecane, and butadiene polymers and copolymers.

Fluid chocolate is treated prior to moulding and covering operations by dividing it into at least two portions under thermal control which are simultaneously cooled to at least two different substantially predetermined temperatures, the portions being subsequently recombined and intimately mixed to a mass submitted to thermal control and discharged for further treatment. Vessel 1 is maintained at a suitable temperature by hot water circulating inside the doubled wall 2 and the chocolate mass therein is stirred by vane 3. Chocolate is fed from vessel 1 through conduits 4 and 5 respectively into coolers 6, 7 through which it is fed by screws 8, 9 to chamber 10 where the chocolate from both cylinders 6, 7 is mixed by vane 11. From chamber 10 the chocolate passes through pipe 12 from which it may pass through a bypass pipe 13 controlled by a valve 14 if it is desired to return the chocolate to vessel 1. In cylinder 7 the chocolate is cooled to a lower temperature than that of cylinder 6, where the minimum is 33-34‹ C. A thermo-adjusting device 15 has its sensitive end 16 in contact with chocolate cooled by cylinder 6 and maintains the chocolate at a predetermined temperature, as set by an index on the dial of device 15, through wires 17 connected to an electro valve 18 which regulates the flow of cooling liquid to the container. A similar device 15a controls the temperature of the chocolate in cylinder 7. A thermometer 23 is provided which indicates the final temperature of the chocolate and this may be adjusted by adjusting the devices 15, 15a.
